webpack.config.js

const webpack = require('webpack'); const nodeenv = process.env.node_env || 'production';  // entry - u want start app // loaders - how should handle spec file module.exports = {   devtool: 'source-map',   entry: {      filename: './app.js' }, output: {     filename: '_build/bundle.js' }, module: {     loaders: [         {             test: /\.js$/,             exclude: /node_modules/,             loader: 'babel-loader',             query: {                 presets: [["es2015", { "modules": false }]]             }         }     ] }, plugins: [     // compress js - uglify js     new webpack.optimize.uglifyjsplugin({         compress: { warnings: false },         output: { comments: false },         sourcemap: true      }),     // set actual environment - env plugin     new webpack.defineplugin({         'process.env': { node_env: json.stringify(nodeenv)}     })   ] }

app.js

import { uniq } 'lodash'; import insane 'insane'; import jsonp 'jsonp';  console.log('hello world!'); const ages = [1, 1, 4, 52, 12, 4]; console.log(uniq(ages));

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...
